To all whomit'may concern: v

Be .it known that I. V}. a; citizenof the United States, 'resid in at Art; lanta, in. the county of. Eul tonand tate 02 Georgia, have-invented new and usefulImprovemc'nts in Electromagnetic Motors-of which the following is a specificat on.

This invention relates to improvements in electro-magnetic motors and it proposes a motor in which the stator consists; of an electrounagnet having two poles of opposite a permanent magnet which rotates with relation to the electro-magnet.

I have found that a motor of th tylple herein proposed is capable of many use l applications, serving these applications with-- much greater efiicien'cy than'any other type of motor of which I amaware. The fact that the improved motor is capable of highly eflicient use in several 'difierent applications not inhefre in the generally similar motor of known form, via, wherein the rotating electro-magneticarmature is combined with a permanent magnetic fluid. I

The first characteristic which peculiarly adapts the motor for certainuseful applicahigh power with relation to its speed and its speed is very-constant. due to the weight of the revolving permanent magnet which travels at slower speed but has greater motnentum than the electro-magnetic armature previously employed. 3 This characteristic adapts the motor to those environments in which a slow speed-with a comparatively tain constructions of revolving advertisingsigns must, to be elficient as advertismgmerate of speed and yet a comparatively high power is required to produce this rotation. The motor which forms the subject of the present application may be used .with advantage in these, as wellas various other, environments. which will readily suggest themselves.

- The second characteristic which peculiarly applications is that the rotor is permanently magnetized instead of intermittently or variably magnetized as heretofore, thus fur nishing, so to speak, a moving constant magnetic field;' a characteristic which prov Specification of Letters Patent; lcppsicmtlon'. filed magnet ,18,

An embodiment of the invention is'ilhas traced in the accompanying drawings, whereinv 7 Figure" I is a side elevation of the-inn proved motor thereof; and Fig. 3" is a detail sectional view of the electromagnetic armature.

It is bf course apparent that the rotation of the pennanent magnet is caused by the actidn of its lines of 7 force which constantly seelrto adjustrthemselves to a variable orintermittent field.
